NOTES
- The above data is valid in free ¿ eld condition, because it is measured in a semi-anechoic room. If the
sound is measured under actual installation, the measured value will be higher due to environmental
noise and sound reÀ ections. Choose the installation location carefully and do not install the unit in a
sound sensitive environment (e.g. living room, bedroom, ...).
- dBA = A-weighted sound pressure level (A scale according to IEC).
- EW = entering water temperature - LW = Leaving water temperature
- Reference acoustic pressure 0dB = 20 Pa
- Sound pressure level of low sound mode n°2 and n°3 is lower than n°1
- (*) Does not occur simultanously on all sides.
